Addict RC

road4899–14999 USD

Origin

2007. The Addict was a direct evolution of Scott's CR1 (880g frame) — the first production road bike to break the 6kg barrier. It dominated the professional peloton with Columbia-HTC and Mark Cavendish. The 'RC' designation emerged formally with the disc-brake era but the Addict name has been synonymous with lightweight road racing since 2007.

Specifications

Frame: HMX-SL carbon. Frame weight: 599g (size M, unpainted). Fork: 270g (size M). Frame kit total: 869g — lighter than most high-end road frames alone. HMX carbon. Frame: 650g (size M, unpainted). Fork: 295g. PP Mandrel (polypropylene bladder) moulding — completely hollow frame with no dead-end tube segments. Internal surface as smooth as external. Bladders fully removable after curing. Tube walls down to 0.6mm. Press-fit BB86 (not T-47, not UDH — intentional weight choice) Non-UDH proprietary (1.1g lighter than previous generation) 28 (Ultimate) / 30 (all others) Narrowed for 10% lower frontal area vs previous gen via new internal cable routing path 27.2mm eccentric profile at top (vs standard 28.6mm) — aids aero without sacrificing stiffness Fully internal. RC 20 and below: under-stem entry. RC 10 and above: fully internal through headset. SP-R101-CF comfort seatpost (RC 10 and below); SP-R101-SL lighter version (Pro and above). Hidden magnetic bracket for optional Syncros rear light. Syncros IC-R100-SL integrated bar/stem. Subtle drop flare for aero-brake lever alignment. 8 stem lengths (70–140mm) × 5 bar widths (360–420mm). T25 tool hidden in bar end. Geometry identical to Foil RC ('cockpit stack/reach' concept introduced to compare contact points between aero and lightweight bikes). Longer reach than most road bikes in category.
Weight: kg
Drivetrain: SRAM Red AXS 12-speed + Quarq power meter (Ultimate); Shimano Dura-Ace Di2 12-speed (Pro/Team); Shimano Ultegra Di2 12-speed (RC 10/20); Shimano 105 Di2 12-speed (RC 30). All electronic.
Brakes: Hydraulic disc, flat-mount. SRAM Red AXS or Shimano hydraulic per groupset. Through-axle front and rear.
Wheels: Syncros Capital SL 40mm full carbon (Ultimate); Syncros Capital 1.0S 40mm carbon (Pro/Team/RC 10); Syncros Capital 1.0 carbon (RC 20/30). Tubeless-ready.

The verdict

+Strengths

5.84kg complete bike (Ultimate) is the lightest production road bike with disc brakes — verified on scale
PP Mandrel construction produces cleaner frame interior than any previous process — reduces resin waste and weight equally
HMX-SL at 599g frame is lighter than the fork of many competitor bikes
Geometry aligned with Foil RC — riders can switch between platforms without position change
34mm tyre clearance is generous for a pure lightweight platform — comfort significantly improved vs 28mm previous gen (36% per Scott's data)
Cockpit (IC-R100-SL) is 40g lighter than predecessor with same stiffness
All 6 builds include internal routing, carbon frame, disc brakes — no alloy option pollutes the lineup
Confirmed sub-5.9kg at Velo/Escape Collective scale test — not just claimed weight

−Weaknesses

Ultimate at $14,999 / €12,999 is among the most expensive road bikes ever produced — more than Trek Madone SLR, Specialized S-Works Tarmac SL8
Press-fit BB86 (not T-47) criticised by some mechanics and tech commentators — durability concerns in wet conditions
Non-UDH proprietary hanger — ecosystem compatibility reduced
Steerer diameter reduced to 27.2mm at top — some mechanics uncomfortable with unusual spec
7.7kg at RC 30 spec is on the heavy side for a 'lightweight bike' at this price ($4,999)
Ultra-thin frame walls (0.6mm) raise long-term durability questions in crash scenarios

Did you know

01The Gen 4 Addict RC at 5.84kg is the same weight as the 2007 original — despite adding disc brakes, electronic shifting, 30mm tyres, deep carbon wheels, and full internal routing
02PP Mandrel moulding is borrowed directly from Scott's mountain bike technology — the same technique used on Spark/Genius frames, now applied to road bikes
03The 599g frame is lighter than Scott's own claims for the fork alone on previous-generation bikes
04Frame tube walls down to 0.6mm — thinner than a standard sheet of copy paper
05Non-UDH and press-fit BB86 are deliberate weight choices — each component was individually reweighed including the rear derailleur hanger (1.1g lighter version)
06Anna Kiesenhofer won the 2021 Olympic Road Race gold on a Scott Addict RC — one of the biggest upsets in Olympic road cycling history
07The 'cockpit stack/reach' concept was introduced by Scott to allow direct geometric comparison between the Addict RC (lightweight) and Foil RC (aero) — they offer identical rider position despite different frame geometries
08Mark Cavendish won 6 stages of the 2009 Tour de France on the Addict — an all-time record for a sprinter winning on a lightweight climbing platform
09The integrated T25 tool hidden in the handlebar drop can adjust every bolt on the bike including wheel thru-axles
